MOP-HEAD.

Specification of Letters Patent.

Patented Apr. 13, 1915.

Application filed February 12, 1914. Serial No. 818,291. v

To all whom it may concern:

Be it known that I, HENRY I. DAVIS, a citizen of the United States,residing at Ann Arbor, in the county of l/Vashtenaw and State ofMichigan, have invented certain new and useful Improvements in Mop-Heads; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in mop heads of that class whichconsist of a clamp or wire fixed to a suitable holder or handle.

The object of the invention is to provide a simple and efiicient deviceof this character especially designed for use in connnection with whatare known as dustless mops.

With this and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and claimed.

In the accompanying drawings :Figure 1 represents a perspective view ofthis improved mop head with the jaws in open position ready to receive amop; Fig. 2 represents a front elevation with the jaws in closedposition; and Fig. 3 represents an edge or side elevation thereof.

This improved mop head is composed of four parts, a fixed jaw or frame 1of malleable iron or iron wire having a shank 2 for attachment to ahandle H; a movable clamping jaw 3 for cooperation with said fixed jawand which is hinged to said jaw 1 and spring wire catches 4 and 4 forholding said movable jaw yieldably but firmly in engagement with the jaw1.

The heavy wire forming the fixed jaw 1 is bent with its ends extended inparallel lines to a certain point to form the shank 2 of the jaw 1 fromwhich they diverge from each other in opposite directions and inalinement to form an inner cross bar 5. From the ends of this cross bar5, the wire is extended forwardly to provide side members 6 and 7 forthe jaw 1 and these side members have offset loops 8 and 9 arranged neartheir inner ends and disposed oppositely to each other to form bearingsfor the clamping jaw as will be hereinafter described. The forward endsof the side members 6 and 7 are extended laterally outward in oppositedirections to form short cross bars 10 and 11 from the outer ends ofwhich extend parallel arms 12 and 13 arranged in planes at right anglesto the bars 10 and 11 and which are connected at their outer ends by across bar 14.

From the above description, it will be seen that this jawl is formedfrom a single piece of wire bent in the manner described with itsterminals arranged in close prox imity in parallel relation to form theshank 2 which is adapted to be driven into one end of the handle H andsecured therein in any suitable mannerr The movable clamping jaw is hereshown substantially rectangular in form comprising side members 15 and16 and outer and inner cross bars 17 and 18 respectively. This jaw 3 isalso preferably constructed ,of heavy iron wire one end of which is bentto form an eye 19 arranged at the inner end of the side member 15through which the other end of the wire which forms the end of the rearor inner cross bar extends and is bent laterally to form a hook 20 forholding said ends firmly in engagement to prevent their accidentalseparation.

The inner or rear cross bar 18 of this rectangular clamping jaw 3 ispivotally mounted in the bearings formed by the offset loops 8 and 9 inthe side members 6 and 7 of the jaw l, the inner or rear cross bar 18 ofthe jaw 3 being slightly longer than the space between the side members6 and 7 of the jaw 1 whereby the side members 15 and 16 of the jaw 3 arepositioned outside the side members 6 and 7 of the jaw 1 and are adaptedto overlap the short cross bars 10 and 11 of the jaw 1 and the cross bar14 thereof, the outer or front cross bar 17 of the jaw 3 preferablyextending beyond the cross bar 14 of the jaw 1 to afford means foropening the jaws when desired, the gripping action of the jaws takingplace between the front cross bar 14 of the jaw 1 and the side members15 and 16 of the jaw 3 near their outer ends and between which a dustcloth or mop is adapted to be inserted and firmly held.

The spring wire catches 4 and 4 for bolding the movable jaw yieldably inengagement with the fixed jaw 1 are here shown in the form of coiledsprings 21 and 22 mounted on the inner or rear cross bar 17 of the jaw 3and each having arms 23 and 24 ex tending rearwardly and forwardlyrespectively. The rear arms 23 of the coiled springs 21 and 22 havehooks 25 on their terminals which are engaged with the rear crossbar 5of the jaw 1 on the opposite sides of the handle H. a j

The forwardly extending arms 24 of said springs flare outwardly ordiverge and are provided at their terminals withhooksjflfi which engagethe side members15 and 16 "of the 3 near their outer endsthereby forcingsaid side members laterally into engagement with the jaw 1, the coilsprings 21 and 22 exerting their tension for holding the jaw 3 inengagement with the jaw 1. c As shown the arms 24 of the spring catches4: and 4c" extend obliquely across the side members 15 and 16 of the jaw3 and the hooks or fingers 26' on the terminals thereof bear against theouter faces of said side members. By this arrangement of the springcatches 1 and 4c the rectangular clamping 8 firmly "engages the crossbar 1 1 of the jawl to 'securely hold' a'dust cloth or mop between saidelements and when it is-desired to remove the mop, all that isnecessaryisto grasp the front cross bar'17 of the jaw 3 which extendsbeyond 'the cross bar 14' and force'said jaw 3 laterally outward againstthe tension of-the spring catches 21 and 22. When this cross bar isreleased, these 'spring'catches will force it into closed position. 1

I claim as my invention A mop head comprising a stationary jaw composedof a single strand of wire designed to form substantially a rectangularmember, the side arms of said member being offset rearwardly adjacenttheupper ends thereof to form loop-like bearings, the lower por- Oopiesof this patent may be obtained for tions of said side arms being offsetlaterally .in the plane of the member to form a broadened lower end onthe stationary jaw, a movable jaw composed of a single strand of wirebent to form substantially a rectangular .:member, the innercross barthereof being ably with the inner cross bar of the stationary jaw andthe outer opposed end coils of said springs being extended aconsiderable distance and engaged with the side bars of the movable jawadjacent the outer end of the latter, whereby to retain said movable jawin the bearings and yieldingly retain the same in contact with thebroadened outer portion of the-stationary jaw.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
